To all when it may concern:

Be it known that l, Lioxnn M. WooLsoN, a citizen oi' the United States, and resident oi Detroit, Wayne ounty, State ot Michigan, have invented certain new and useful improvements in IHydrocarbon Motors, of which the followinpr is a specitication.

This invention relates to hydrocarbon motors and particularly to 1n uns 'for heating the mixture passinpv Vfrom the carburetor to the motor.

The invention is particularly adapted for motors using lou' grades ci fuel, even as lov: as kerosene,

Une of the objects oi the present invention is to provide a heating means for the mixa ture of a hydrocarbon motor such that the amount of heat will be increased as the quantity of mixture supplied to the motor is in'` reused.

Another object oi" the invention is to pro.- vide a combustion heater for the mixture of a hydrocarbon motor and controlling means therefor which' will increase the sup ply ot mixture to the combustion heater as the quantity Aoi mixture is' increased to the motor:

Another object of the invention is to provide a combustion heater for the mixture of a hydrocarbon motor with means for in,- creasingr and decreasing the amount of mixturev supplied to the combustion heater, which latter means is controlled, either manually or in rela-tion to some other variable part ot the motor. .A

Other objects of he invention. will appear from the following1 description taken in connection with the drawing which forms a part oi this speciiication and in which the iigure is a vertical section in part elevation through the 4intake showing an illustrative form of the invention.

Referring to the drawing, 10 represents a motor intake pipe which may be secured to the motor as by the ears 11. A carburetor.

12 .is connected to the intake pipe 10 as by the flange and bolt connection `13.

The carburetor 12 may be of any suitable form Vadapted to supply a suitable mixture of gasoiine or kerosene or other-fuel, and air; to' the motor. its upper part and the intake pipe ory header above referred to forni a passage 1li for the mixture which passes through the outlet 15 into the motor. Arranged. injthis passage 14C is a throttle rale. serieu iro. stema. x

valve 16 which may be operated by an arm 17 and a rod 18. rfhis throttle valve constitutes one of the mixture means ot the motor since it controls the quantity ot mixture passing to the motor.

controlling F or determiningw the level of liquid fuel in the carburetor l2 a float chamber' 19 isl connected to the carburetor and provided with a float 20 and Weighted levers 21 operating on a valve 22' which controls the pssage 'Qroin the main fuel supply pipe 2 Said float chamber 19 may also supply a second carburetor 25 which is preferably much smaller than the carburetor 12 and is adapted to supply a small amount of mixture forheating the mixture passing from the main carburetor to the motor. This carburetor 25 has a small fuel tube 2G' extending down into the ioat chamber 19 and a nozzle 27Which is surrounded by an air passage 28 having one or more inlet ports 29 cont-rolled or adjusted by a sleeve 3G surrounding the body of? the carburetor at that pointB i 'throttle valve 31 is arranged in the passage 32 above 'the nozzle 27 and is thereby adapted to regulate or control the supply of. mixture passingy from the carburetorto a pipe 33. Whic leads to a chamber 34: mounted upon or connected to the intake pipe 10 above referred to. The

chamber 311 is shown in heatingrelation to,

the intake pipe 10 and a spark plug 35 or other suitable igniter is arranged in the chamber so that the mixture Whicl enters the chamberv may be'red to produce the required heat. The chamber 34 has an outlet to the interior of the intake pipe 10, a passage 36 of circuitous form being provided for that purpose. Thus the chamber 3ft is under suction from the motor and thus the charge of mixture is drawn into the chamber from the carburetor 25. -The burnt gases fro-mthe chamber 34 are also thus discharged directly into the intake pipe 1() and there mix with the main supply ot mixture passing from the carburetor 12 to the motor. This tends further to heat the latter mixture and thereby assist in volatilization of the liquid fuel. i

As carburetors 12 and 25 are both under suction from lthe motor, when the motor is turned over for starting, mixture will be drawn from both carburetors and the heating act-ion will at @nce start in the chamber los f the throttle 3l is also opened to a similar degree.for-increasing the supply ot mixture from the carburetor 25. throttle 1G is closed. the'throttle 3l will opened it is desirable to increase the heat-v Tol 1n, r capacity ot the combustion. heater. bringr about this result the throttles 1G and 3l areinterconnected as by rodA 3T so that as the throttle 16 is opened to increase the supply of mixture'froin the main carburetor l2.

move' simultaneously with it to cut down the mixture supply from the carlairetor Quand consequently cut down the heat supplied by:

. the combustion chamber 34:.
